NO-1 UK MRI teaching website but low search visits

We are a group of
six highly qualified medical professionals (two doctors, two MSc MRI radiographers
and two general radiographers). We designed ‘mrimaster’ to teach radiologists
and radiographers all around the world. The site was fully launched with high
quality contents in August 2013 (the only MRI teaching website ever made). We are
receiving an average of 500 visitors per day. Out of which more than 250 are
direct visitors and approximately 180 from referrals, adwords and bing traffic.

We are hardly getting
any visitors from Google. We employed a SEO company to do our business. Unfortunately,
they have not done anything except from making some useless back linking. We managed
to clear off almost all the SEO links that they built. Our site was not on the
first three pages neither before nor after the SEO. We are technically very
poor. Could someone help us to find the mistakes in our site?

After spending a few minutes trying to find the root cause of your site's problem, I stumbled upon a few pretty low quality sites that all have an anchor back to your site with the anchor text "what is an mri". I don't know who placed them there (it might have been your SEO) but this is really bad and if I were you I'd spend some time cleaning up these kind of links.

Thank youSir.Gary
Illyes. We did e-mail all the webmasters to remove our link from their web
pages. We are not interested in ranking ‘what is an MRI’. Our site is not to
tell what an MRI is. It is purely to teach people how to scan and how to read a
scan.Our SEO people have done this
to increase our traffic to the site as
they promised when we paid. We will do another set of e-mailing
next week. Can we do anything if they refuse to delete or ask for big money to
remove the links?
